Device and method for straightening ankle joint fracture malunion

Abstract

The invention discloses a device and method for straightening ankle joint fracture malunion, and relates to the field of ectosteal fixers. The straightening device specifically comprises a first supporting rod and a second supporting rod which are connected through a connecting piece, guiding mechanisms mounted between the first supporting rod and the second supporting rod, a screw rod which is inthreaded connection with the first supporting rod and a straightening mechanism mounted below the connecting piece, wherein according to the height of a user, a rotating button is rotated to enable the screw rod to push a reinforcing device, so that the space between the reinforcing device and the straightening mechanism is equal to the space between the waist and the sole of the user; the straightening device can be flexibly adjusted according to the heights of different users, so that the practicality of the equipment is improved, and the application range of the equipment is enlarged; pilefabric binding bands on PE buckles are strained, so that the ankle and the foot of the user are fixed in a PE shoe mold housing; and through the traction of the pile fabric binding bands, the situation that the ankle joint can be limited in a horizontal surface, a vertical surface and a sagittal plane is guaranteed, so that the ankle joint can be effectively straightened.

Description

technical field [0001] The invention relates to an external bone fixator, in particular to an ankle joint fracture malunion correction device and a correction method. Background technique [0002] The ankle joint is composed of the articular surfaces of the lower ends of the tibia and fibula and the trochlea of ​​the talus, so it is also called the talus calf joint. The lower articular surface of the tibia and the medial and lateral malleolus articular surfaces together form the "冂"-shaped joint fossa, which accommodates the trochlear (joint head). Since the trochlear joint is wide in front and narrow in the rear, when the foot is dorsiflexed, the wider front part enters In the fossa, the joint is stable; but in plantar flexion, such as when the narrow rear part of the trochlea enters the fossa when walking downhill, the ankle joint is loose and can move laterally. At this time, the ankle joint is prone to sprains, and varus injuries are the most common. , because the later...

Problems solved by technology

[0003] However, after ankle joint fractures, it is easy to deform and grow during healing. The existing orthotics for the treatment of foot and ankle deformities are generally ring-type external fixators. Flexible adjustment function, lack of flexibility, difficult operation, not conducive to functional training
